Hi everyone, I've had my Arosa for 10 years now (time has flown!) and it still drives very well, a great little car especially for parking! However, recently, it's started to decide to lock/unlock itself continuously, so continuously that it drained my battery. My local garage has disabled the central locking system for the passenger's door and it's now on manual mode, however the driver's door and boot are still on central locking mode and it's still going berserk. Sooo, as I'm not planning to part with my little car just yet, my questions are: 1) does anyone know what could cause this locking/unlocking. 2) And I like to have central locking so, if it was a question of replacing the master lock and whatever motor goes with it, how much would it cost approximately? If anyone, knows the answers (or even one of them) I'd be grateful to know them. Many thanks in advance.
